Clear, shame-free sexual health guidance for gay and bisexual men.
Designed for mobile, and built for your privacy.
PackMap is built for one specific purpose: giving gay and bisexual men direct, actionable sexual health advice.
To keep the guidance fast and practical, everything here is calibrated strictly for penile and rectal biology—from tissue absorption and pH balance to how these systems handle PrEP, DoxyPEP, and lube.
By focusing on one anatomy, we can give you exact, tested mechanics. But it also means this guide has a hard limit. The chemistry of vaginal or neovaginal care is fundamentally different. Applying our lube or douching advice outside of a cis male context won't just be unhelpful; it could cause actual problems.
The takeaway: If your anatomy or your partner's falls outside this scope, treat this guide as partial. The core prevention strategies transfer, but the physical mechanics don't. For excellent trans-affirming resources tailored to trans men and trans women, we highly recommend the Terrence Higgins Trust (THT) Trans and Non-binary Sexual Health Guide.
You need information you can actually trust. Every article here is checked against the latest clinical guidelines (including BASHH, ECDC, and WHO) before it goes live.
Because the science evolves, we evolve with it. When official guidance changes, we update the relevant articles within 30 days. You will always see a "last updated" stamp on every page so you know exactly how current the advice is.
Your health is your business, and your data is yours alone. PackMap runs on a strict privacy-first model. We don't want your data, and we don't track it.
The only things stored on your device are your language preference, your theme setting, and your offline article cache. That information never leaves your phone, and you can nuke it completely at any time by going to Settings → Clear All Data.
We are always looking to make this better. For clinical corrections, general suggestions, or if you'd like to help translate PackMap into other languages, reach out to us at hello@packmap.net
